Window and Door Installation


“The right way and the wrong way”

There are several different ways to install a window, but there is only one way to install it correctly. Home construction has really changed over the last 100 years. Throughout the different eras home builders have used a variety of methods to install windows and doors. We are experienced in using the proper techniques that are correct for each and every installation.

Insert Install

This is very common for homes built from 1900-1960. The types of windows you see in these homes are generally wood sash windows with rope and pulleys, or a metal jamb liner. They will normally test positive for lead paint as well. When replacing this style of window it is VERY important to follow the lead safety procedures. This ensures that we don’t contaminate your home and spread harmful lead dust and particles. We are a LEAD CERTIFIED contractor. We follow the guidelines in order to protect you as well as ourselves.

For this type of installation we will typically order a sloped sill adapter for the sill and replace the interior stops in primed or stain-grade. It’s important to order the correct size. We can help you select the right product for your needs such as a vinyl or wood option to maintain the beauty and traditional style of the period.

Nail-fin Cutback:

This is common for homes built from the 1960’s-present day. In this type of construction the outer nailing flange of a window is used. When a home is built, it is framed, there is a sub-sheathing that is applied (a type of vapor barrier), and then the siding is installed. The existing nailing fin of the window is either applied directly to the stud or the sub-sheathing. Then the siding or trim covers the flange.

We cut the siding or trim back to access the nailing fin in order to remove the existing window. We incorporate our flashing, metal z-flashing, caulking, and trim in a way that ensures you that your windows will be performing great well into the future.

Some other contractors will cut the nailing fin off. In the industry this is referred to as a “glue and screw”. This method is not recommended by the manufacturer and relies on the exterior caulking to prevent water infiltration. Would you want a single bead of caulking to be the only barrier from water entering the wall cavity of your home? Here is where you see the “right way vs wrong way”.
